Telepathic genes recognize similarities in each other

Genes have the ability to recognise similarities in each other from a distance, without any proteins or other biological molecules aiding the process, according to new research published this week in the Journal of Physical Chemistry B.

Novel method for assigning probabilities to human protein interactions

The Stowers Institute's Proteomics Center has published a novel method of using normalized spectral counts derived from a series of affinity purifications analyzed by mass spectrometry (APMS) to generate a probabilistic measure of the preference of proteins to associate with one another.

Researchers unravel mystery of cell division

Experts in mitosis (cell division) at the University of Virginia Health System have made discoveries that explain how one protein the kinase Aurora B could have such a large role in guiding and policing the process of cell division.

Protein that controls hair growth also keeps stem cells slumbering

Like fine china and crystal, which tend to be used sparingly, stem cells divide infrequently.

Researchers identify five genes with possible protective capabilities against a Parkinson's disease trait

University of Alabama researchers have identified five genes within animal models displaying protective capabilities against a hallmark trait of Parkinson's disease.

Evolutionary 'battle scars' identify enhanced antiviral activity

Rapid evolution of a protein produced by an immunity gene is associated with increased antiviral activity in humans, a finding that suggests evolutionary biology and virology together can accelerate the discovery of viral-defense mechanisms, according to researchers at Fred Hutchinson Cancer Research Center.

Deafness and seizures result when glutamate protein deleted in mice

Scientists have discovered that mice genetically engineered to lack a particular protein in the brain have profound deafness and seizures.

Quality control mechanism tags defective sperm cells inside the body

Defective sperm cells do not pass through the body unnoticed. A new University of Missouri study provides evidence that the body recognizes and tags defective sperm cells while they undergo maturation in the epididymis, a sperm storage gland attached to the testis.

Genetic difference predicts antidepressant response

Researchers have identified subtle genetic variations that predict the efficacy of two widely used antidepressant drugs.

Evolutionary phenomenon in mice may explain human infertility

Scientists at the University of Liverpool have found that field mice have evolved a unique way of ensuring faster fertilisation, a phenomenon which could explain some cases of infertility in humans.

Engineers use blood's hydrodynamics to manipulate stem, cancer cells

A tiny, implantable device has pulled adult stem cells out of a living rat with a far greater purity than any present technique.

Cigarettes leave deadly path by purging protective genes

A University of Rochester scientist discovered that the toxins in cigarette smoke wipe out a gene that plays a vital role in protecting the body from the effects of premature aging.

Antioxidants such as vitamins C and E don't prevent pre-eclampsia

Taking vitamins C or E during pregnancy will not reduce a woman's risk of experiencing pre-eclampsia, a Cochrane Systematic Review has concluded.

Adaptive functional evolution of leptin in cold-adaptive pika family

Researchers at the Northwest Institute of Plateau Biology, Chinese Academy of Sciences have put forward the viewpoint for the first time that adaptive functional evolution may occur in the leptin protein of the pika (Ochotona) family, a typical cold-adaptive mammal.

New anticancer drugs may block HSP90-IP6K2 protein interaction involved in cell death

Johns Hopkins researchers have discovered a previously unsuspected mechanism of cell death that may afford a new way to find and develop stronger yet less-harmful anticancer drugs.

New method for measuring protein synthesis

In a major breakthrough for future research and drug development, a team of Los Angeles Biomedical Research Institute (LA BioMed) investigators developed a new, more reliable method for measuring protein synthesis and turnover, processes that are critical to understanding cellular functions.

Genetic switches could lower cost of producing drugs, proteins

Bacteria have evolved complex mechanisms called quorum sensing systems that provide for cell-to-cell communication, an adaptation that allows them to wait until their population grows large enough before mounting an attack on a host or competing for nutrients.
